Default Reaper weird sizzling phase sound issues

Hey all,

Today I tracked the second guitar of a band I'm recording when I suddenly heard a very weird sound when playing back some clips.

All the guitars are dual miked and checked carefully for phase issues.
But when playing back I heard a very awkward phase/sizzling noise when playing back the two mics together.
On there own they sounded fine.
I thought maybe something was wrong with one of my cables or something but then I realized the exact same sound was also present in recordings from the other day before that where previously NOT there...

I always make backups every day so before going nuts I checked my backup from the same project from yesterday and that weird sound is NOT there in the backups file...
It seems only in that project (song) the other ones seem ok, so yeah this is not related to the recording, this must be something that reaper is doing somehow...

I made a screen capture video to make extra clear what the problem is.

Please help, I'm desperate

Phase reversal on one track?

Well, here we can use math: let's take 2 functions(our waveforms) and sum up them(e.g. X and X+0.1), so we have a new function, i.e. our output, which looks like 2X+0.1. Should it work strange? Yes, it should. How to avoid this(in any DAW):
1. Move a little bit one of the item either to the left or to the right and/or use phase-invert button on one of the tracks.
2. Profit.

Thank you for correcting my error with the technical definition. I'm getting my technologies mixed up.
